My video is too big to upload

 To help maintain the smooth functionality of the app, we have restricted the video uploading to a maximum of 60 seconds. However you can add as many clips to your chats as you like.

If you can retake the video, do this in the app rather than filming with the phone's camera and then uploading. If you are unable to retake the video, you will need to use your phone's functionality to cut the clip into segments smaller than 60 seconds.
